Count the Cows

Players keep a running tally of the cows (or sheep or red cars) they see on their side of the car. Pass a cemetery and the player on that side of the car loses all their cows and has to start over. Make the game more fun by trying to distract other players so they miss cows and by allowing 50 bonus points for unusual sights.

Road Sign Math

Ask kids to add up or subtract the numbers they spot on road signs, route signs, billboards, or license plates. Keep it easy for little ones; bump it up for kids who can keep double or triple digits in their heads.
